Markers are a tool that can help you to determine signal characteristics for each mea-
surement point displayed on the trace. They indicate the horizontal and vertical coordi-
nates of trace points, for example the frequency and level measured at a certain trace
point.
The R&S
FPC has six markers, five of which can be used as either markers or delta
markers. Markers show absolute values, delta markers show values relative to the first
marker (marker 1 or "M1"). The first marker (reference marker) is always a normal
marker.
The horizontal position of a marker is represented by a vertical line which extends from
the top to the bottom of the diagram area (continuous lines for markers and dotted
lines for delta markers). The R&S
FPC also draws a marker icon at the bottom of the
line to indicate the position of the marker ( ). The currently selected marker is indica-
ted by a line drawn around the icon ( ). The icon also contains information about the
marker type: "M" for marker, "D" for delta marker, including the marker number ("M1" to
"M6" and "D2" to "D6").
The vertical position of the marker is represented by a small horizontal line on the trace
itself.
